python - 如何直接使用python-selenium预期条件函数？

Question

对于 python-selenium 实现，你有 expected conditions通常在 WebDriverWait 构造中使用:

element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "myDynamicElement"))

我想直接使用此条件，而不使用 WebDriverWait。但做一个简单的

element = EC.presence_of_element_located((By.ID, "myDynamicElement"))

似乎不起作用。那么如何做/使用它呢？

Answer 1

然后您可能想要构建一个自定义方法来运行代码块

def try_bool(attempts = 10, duration = 0.2, interest = True)
  count = 0
  item_of_interest = null
  while item_of_interest == interest || count == attempts
    item_of_interest = interest
    time.sleep(duration)
    count += 1

element = driver.find_element_by_id('locator')
try_bool(10,1,element.is_displayed())
